In an innovation project, Vitesco Technologies has now developed the prototype of the E-axle control module. The electrohydraulic control module shown for the first time in Berlin provides several scalable functions: Essentially, it provides oil cooling for high speeds which makes it possible to utilize the maximum output of an electric motor to a larger extent than today as continuous power. On top of that the module can provide oil for lubrication purposes. Further functions are to be integrated in three scalable expansion stages with additional actuators: This includes safety functions for automated driving, and the option to switch to energy-saving “sailing” without regenerative braking when the battery is fully charged. Further choices are additional clutches for torque vectoring and the possibility to utilize the module for installing a so-called “dry” rear axle with electrically actuated brakes.
